        Description
        ===========
        
        A class containing a collection of text line formater methods.
        Each method get the same signature (except ``dictionary`` and derived).
        
        **Mandatory inputs**:  any object with ``__str__`` method or list of objects.
        
        **Output**: string of fixed length.
        
        
        Simpe context
        -------------
        
        The string is formated in a conceptual zone of given ``length``.
        On both sides, there is paddings (see ``pad`` argument), which are extra spacing, reducing the content zone.
        Left and right paddings can be individually specified using ``l_pad`` and ``r_pad`` arguments respectively.
        The content can be shifted of a signed value (see ``shift`` aguement) inside the content-zone.
        If the content is a list of elements, one can specify the separator using ``sep`` arguement.

         │<┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄length┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄>│
         │         ┆                          ┆         │
         │<┄l_pad┄>┆       content-zone       ┆<┄r_pad┄>│
         │         ┆                          ┆         │
         │<┄┄pad┄┄>┆    <┄┄ - shift + ┄┄>     ┆<┄┄pad┄┄>│
        
        Example::
        
          input = ["elt1", "elt2", "elt3"]
          length = 18
          pad = 2
          sep = "*"
          output =   "  elt1*elt2*elt3  "
        
        
        
        Multiple context
        ----------------
        
        In multi context, each element of given contents are formated in as many content zones.
        The previously described arguments are still available, and affect the main content zone (and not the contents).
        See ``length``, ``pad``, ``l_pad``, ``r_pad``, ``shift`` and ``sep``.
        All these arguments can be applied separately on each content zones using there plural forms.
        See ``lengths``, ``pads``, ``l_pads``, ``r_pads``, ``shifts`` and ``seps``.
        If a single value is given to these plural form, it will be applied to all the content zones.
        If one wants to set separate values for each plural form, a list must be given.
        Also, if one want to keep the default for some content zones, a None value must be filled at corresponding positions.

        Table context
        -------------
        
        Table-context is very similar to multi-context. Main differences are only some arguments with differents default values : ``pads`` is set to 1 and ``tip`` and ``sep`` are set to '|' (pipe).

           │    elt1 elt2     │  > center (c)
           │                  │
           │elt1 elt2         │  > left (l)
           │                  │
